MOUNTD(8)               FreeBSD System Manager's Manual              MOUNTD(8)

NAME
     mountd -- service remote NFS mount requests

SYNOPSIS
     mountd [-2dlnr] [-p port] [exportsfile]

DESCRIPTION
     Mountd is the server for NFS mount requests from other client machines.
     It listens for service requests at the port indicated in the NFS server
     specification; see Network File System Protocol Specification, RFC1094,
     Appendix A and NFS: Network File System Version 3 Protocol Specification,
     Appendix I.

     The following options are available:

     -2      Allow the administrator to force clients to use only the version
             2 NFS protocol to mount filesystems from this server.

     -d      Output debugging information.

     -l      Cause all succeeded mountd requests to be logged.

     -n      Allow non-root mount requests to be served.  This should only be
             specified if there are clients such as PC's, that require it.  It
             will automatically clear the vfs.nfs.nfs_privport sysctl flag,
             which controls if the kernel will accept NFS requests from
             reserved ports only.

     -p port
             Force mountd to bind to the specified port, for both AF_INET and
             AF_INET6 address families.  If mountd cannot bind to this port,
             an appropriate error will be recorded in the system log, and the
             daemon will then exit.

     -r      Allow mount RPCs requests for regular files to be served.
             Although this seems to violate the mount protocol specification,
             some diskless workstations do mount requests for their swapfiles
             and expect them to be regular files.  Since a regular file cannot
             be specified in /etc/exports, the entire file system in which the
             swapfiles resides will have to be exported with the -alldirs
             flag.

     exportsfile
             Specify an alternate location for the exports file.

     When mountd is started, it loads the export host addresses and options
     into the kernel using the mount(2) system call.  After changing the
     exports file, a hangup signal should be sent to the mountd daemon to get
     it to reload the export information.  After sending the SIGHUP (kill -s
     HUP `cat /var/run/mountd.pid`), check the syslog output to see if mountd
     logged any parsing errors in the exports file.

     If mountd detects that the running kernel does not include NFS support,
     it will attempt to load a loadable kernel module containing NFS code,
     using kldload(8) by way of vfsload(3).  If this fails, or no NFS KLD was
     available, mountd exits with an error.

FILES
     /etc/exports         the list of exported filesystems
     /var/run/mountd.pid  the pid of the currently running mountd
     /var/db/mountdtab    the current list of remote mounted filesystems

SEE ALSO
     nfsstat(1), exports(5), kldload(8), nfsd(8), portmap(8), showmount(8)

HISTORY
     The mountd utility first appeared in 4.4BSD.

FreeBSD 4.10                    April 28, 1995                    FreeBSD 4.10
